BISCUIT OR LIKE-EMBGSSING vVANI) CUTTING lVIAClEINIl.y

Application led December 22, 1820, Serial Na 432,588, and in GreatBritain June 30, 1919.

(GRANTED `UNBER 'THE PROVISIONS 0F THE ACT l(JF MARGH, 1921, 41 STAT.L., 1313.)

rlhis vinvention is `directed .to lbiscuit. or like embossing andcutting-machines of the type shown in Patent No. 1,231,817 issued .'luly3, 1917, and is particularly directed to lprovidingA .adjustable `stopstor 'limiting the descent of the ejectors, so that when 'the cuttercross head descends to the cut-'ting point.l vthe ejectors are held Youtot' VContact with the biscuits unt-il the cutter cross head rises.

More specifically, Vthe' invention provides duplicate sets or' wed-gesarranged in co operating pairs, and manually adjustable to interrupt thedescent ot the ejectors at the desired point.

The inventionv is illustrated in the accompanying drawings, in which: n

Figures Pand 1b, taken together, on the line AMA, show a front View ot'the machine which could not be satisfactorily shown on one sheet.

Fig. 2 is V'a vertical cross section of the saine, illustrating `moreparticularly the -arrangement and meansl t-'or opel-ating the wedges.

Fig. 3 is a longitudinal section ot the cutter and ejecting mechanism.

'lhe improvement is 4particularly directed to a machine ot this type,wherein side bars 9, one on each side, which support or are carried incross plates 8, are loosely7 connected to the cross head 2. Rods 6carried in the cross plates 8 pass through casings 5 lined on the sidesof the cutter head 2, and are provided with adjusting nuts 7 below thecasings, tension springs 4 being arranged .in the casings. The embossingcross head is indicated at 1, and the frame bars, in which the cuttercross head works, are indicated at 10. The ejector mechanism A iscarried on bolts 20 which pass through slots 21 inthe cross head 2, andare provided above the plates 8 with adjusting nuts 22 and lock nuts 23.

The ejector mechanism A is carried on bolts 20, through the medium of aplate 25, to which the bolts are connected by yoles 26, supplementalbolts 28 extending from the plate 25 to the ejector mechanism. Yolres 27connect the cutters B to the cross head 2.

The above description is a brief outline of sulicient of the ordinaryparts `of a machine ot the type to which the present invention isapplied, for an understanding oit the invention, the detail or' whichwill be now described. l

The bars 9 are provided with lined vdepending stops 13, and cooperatingtherewith are stops 12 mounted at each side of y'the machine on theupper surface of an upper wedge member 13X, having its Iinclined surtaceresting upon the similarly inclined surface `ot an'adjustable lowerwedge member, the stops 12, which are in' the form of rods,lbeing/guided in 'hollow guides 15 secured to the insides ot the frames10.

The lower wedges 14 `are supported and move on rollers 16, carried `byspindles 17 secured 'to lthe trames r10, and these lower wedge membersare adjusted longitudinally by appropriate. operation of adjusting .nuts17X engaging a threaded spindle 18 projecting from the lower wedgemember, with the adjusting nuts arranged on opposite sides ot aflinedbracket 19, through which the spindle 18 loosely passes.

Obviously, 'by adjusting the `lower wedge members, the descent of theejectorsrcan be limited tothe extent desired through cooperationot thestops 12 and 18', and furthermore as .independent wedge mechanism isprovided on each side ofthe machine, the adjustment maybe such as topermit the descent ol' the cross bars at an angle to the cutting tableto regulate the level of` the ejector plate.

To use the cutters and ejector mechanism for cutting biscuits, theejecting bolts 20 are passed through slots 21 in the cross head 2, andscrewed through the collared nuts 22 fixed on the bridges 8, and thenthe upper wheel nut 23 is screwed in position onto the end of the bolts20; and the ordinary cutters B being placed in position and secured tothe cross head 2, they are lowered into the cutting position with theejecting plates resting on the cutting web. When in this position, thelower end of the nut 22 should rest on the cross head 2, and then bymeans of this nut the ejecting plate should be raised about a quarter ofan inch away from the cutting web table; and then they are locked inthis position by means of the lock nuts 23 on the top of the nuts 22.

The spring adjusting cross plates 8 are set so that there is say a spaceof about three eighths of an inch between the nut bottom of the nut 22,and the cross head 2, whereupon the rods 12 are so adjusted as to be intouch with the tips of the stops 13 on the bars 9.

In this condition the springs 4 are placed in position and compressed byscrewing up the nuts 7 on the rods 6 until they are say in this case,nine sixteenths of an inch shorter than when fully extended, and remainin this state, when the ordinary cutters are out of gear, and theembossing cutters are being used on the machine.

On each end ot the cross bars 9 a distance piece 9 is provided, whichprevents them from approaching the cross head 2 nearer' than isdesirable.

Claims:

1. In a biscuit embossing and cutting machine, a movable cross head foroperating the cutters, ejectors, bars carrying said ejectors and adaptedto be operated by the cross head, and adjustable wedge mechanism tolimit the descent of said bars in the movement of the cross head.

2. In a biscuit embossing and cutting machine, a movable crossA head,ejectors, bars carrying said ejectors and adapted to be operated in themovement of the cross head, tension springs providing` a yieldingconnection between said bars and cross head, stops connected with saidbars, cooperating stops movable in the frame of the machine, and wedgemembers to actuate said latter stops to limit the descent of said bars.

3. In a biscuit embossing and cutting ma chine, a movable cross head,ejectors, bars carrying said ejectors and adapted to be operated in themovement ot the cross head, tension springs providing a yieldingconnection between said bars and cross head, stops connected with saidbars, cooperating stops movable in the :trame of the machine, wedgemembers to which said cooperating stops are connected, and adjustablewedge members cooperating with the first mentioned wedge members to movethe same and thereby the cooperating stops to determine the descent ofsaid bars.

4:. In a biscuit embossing and cutting machine, a movable cross head,ejectors, bars carrying said ejectors and adapted to be operated in themovement of the cross head, tension springs providing a yieldingconnection between said bars and cross head, stops connected with saidbars, cooperating stops movablein the fra-me of the machine, and wedgemembers arranged in cooperating pairs at each side ot the machine toactuate the cooperating stops to limit the descent of the bars.

5. In a biscuit embossing and cutting machine, a movable cross head,ejectors, bars carrying said ejectors and adapted to be operated in themovement of the cross head, tension springs providing a yieldingconnection between said bars and cross head, stops connected with saidbars, cooperating stops movable in the frame of the machine, and wedgemembers arranged in cooperating pairs at each side of the machine toactuate the cooperating stops to limit the descent of the bars, eachpair otwedge members being independently adjustable to thereby vary thedescent of each side of the ejectors at will to regulate the level ofthe ejectors.

In testimony whereof we have signed our names to this specification.
